Mine was spotless as well. Still a POS. kinda hard for it to get dirty when it won't shoot. Running $12 a box mini mags defeats the purpose of a 22 fun gun. Sold mine to a pawn shop luckily I only took a $50 loss on it.
I've sold guns that way. As long as it ships to an FFL you have no worries. Make them pay up front then ship. It's the same as buying something off gun broker.
I run a pro on one of my rifles but I've also got a Trijicon Rx30 that may be worth you looking into as well. Battery life is never an issue if you don't need them
For people who are just getting into reloading now empty shelves are exactly what they are going to see. Your a little late to the game. For those of us who learned from the last panic we bought what we were going to need when the last panic died down and have more than enough to get by.
I used to like my glocks. They were my first 2 semi auto handguns. Now the G19 is on the chopping block. Springfield armory and H&K make much better pistols.
